Feedback mix factor for the output of the State Variable
Filter.
Feedback mix factor for the output of the Eects chain. The
reverb amount in the feedback can be set by the “Reverb
Amount” fader independantly. Since the signal is mono-
phonic, such feedback will cause intermodulation between
the voices.
Controls the amount of reverb in the feedback indepen-
dantly from the Mix in the Reverb section.
0.0 %: dry, no reverb signal
50.0 %: mix of 50 % dry and 50 % wet signal
100.0 %: wet, 100 % reverb signal
Input gain [in dB] of the sine shaper stage. Higher gains will
create more distortion and harmonics.
Amount of folding back of the shaper curve for high input
amplitudes.
0.0 %: flat saturation, no folding
100.0 %: fully folded back (periodic sine curve)
A higher amount of folding leads to a soer but more nasal
sound.
Asymetry of the shaper curve, generating even (2nd, 4th, ...)
harmonics. At higher values, it becomes a parabolic curve
that shis the frequency of the fundamental to its double.

Amount of splitting of the cutos of the two 2-pole filters.
Half of the value is applied as a positive oset to the adjusted
cuto for the first stage and as a negative oset for the
second stage [in semitones].
The split reduces the strong resonance peak in the 4-pole
mode and allows filter curves with two formants. In band-
pass/bandreject mode it controls the width of the band.
Crossfades between the lowpass, bandpass and highpass
outputs of the two filter stages.
(first stage -> second stage: LP -> LP, BP -> LP, HP -> LP, HP ->
BP, HP -> HP)
At zero, the two 2-pole filter stages are in series forming a
4-pole filter. Positive values crossfade to a parallel structure
where the filter outputs are added. In bandpass mode (L-B-H
= 50.0%), the parallel structure with a negative Spread works
as a band-reject filter. Negative values also crossfade to a
parallel structure, but here the lower filter is subtracted,
which leads to phase cancellations.
Amount of modulation of the cuto frequencies by the
output signals of Oscillator & Shaper A and B, with the FM
A-B knob determining their mix. The amount is relative to the
cuto frequency.
The signal for the FM (cuto frequency modulation) of the
State Variable Filter as a crossfade between the outputs of
Oscillator & Shaper A and Oscillator & Shaper B.
Feedback mix factor for the output of the Comb Filter.
